lb all whom t't-may concern:

Be-it'known that I, CHARLES H. PELTON, a residing at S rin'gfield,in the county of Clark and State oFOh1o, have invented certain ncw and useroveinents' in Disk Drills, of which the to owing is a specification, reference being had therein to the accompanying draw 'lngs.

The present invention relates .to-disk drills,

scveral disks to be adjusted in closer-elation one to the other and still allow ample clear-,

. ance between the same. Further, to prothe disk and theboot vide a common means for supporting both and for s'up ortlng from this common means thes'evera ers for cleaning the surfaces of the disks; and

to improve the constructionof these scrapers, to accommodate them to the supports, and to obtain better results in the operation -thereof. A I

With these objects in view, my invention consists of certain novel features of construction to be hereinafter described and then more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a sideeleva'tion of the device on the concave side of the disk. Fig. 2is atop plan View of the device. Fig. 3 is a side elevation of the device on the convex sideof the disk 4 is' a vertical section taken through the isk and bearing. Fig. 5' is a side elevation of the j bearing with the cap. removed. Fi 6 is a. I detail sectionalview of a portion of t e bear-' these drawings, have illustrated the preferredtorm of my invention, in which the referencenumeral' 1 indicates the-dragbar, to the rear end of which is secured a bracket2,

extending rearbar, as shown at 3, and or the disk 4.

wardly from the dra forming thesupport adapted to iit ov'er ther bearing prop'erand form a dust-tightcap 'for the same; vThe bearing consists of a beari -plate6, secured .to the disk 4 by suitable r vets 7 and comprisin a hollow bearing ortion 8 which'is' 'provi ed with an. inwardscrap-- ,The rear' end of the arm Sis in the form of a cap 5,

" ing flange 9 surrounding'thercentralopening in thep ate. 6 and provided on its outer side with arabbeted portion 10., adapted to receive HOMAS MANUFACTURING packlnglliof felt or similar Inal terial to retain the lubricant within the bear-j -extending bear-- ing and to prevent the entrance of dustor dirt thereto. A suitable bearing block 12 fits snugly within the hollow bearlng plate and is provide ortion'8 of the with an annular j groove 13 adapted to receive the inwardl eXtending'flangeQ of the bearin plate. T e

central portion of the hearing lock 'l2ris of 'greaterthickness than the bearin extends through the walls oft e bearing plate and plate and is providedon'its outer face'with an irregular projection or face let-adapted to engage a corresponding recess in the cap 5 the s ape of the projection and recess being such that the'projection can enter the recess in one position only, thus insuringth'e proper positioning of the parts when the same are assembled. f 3

A bolt 14 extends throu'gh'the cap engages a screw-threaded aperture 14 in the bearing block 12 and serves to retain the Sand parts in their assembledo'sition and to se .cure the bearing and its 'sk to the supporting arm 3. A recess .12 and isconnected by channel 15" withan inlet conduit 18, extending through the outer wallof the, cap 5,- and provided with a suitable stop or closure '19.

The bearing block 12 is provided with a radial conduit'16 of suflicient depth to intersect the annular groove 13 and is preferably provided with -a suitable packing 17 and serves to conduct the lubricant from the cup 15to, the bearingsurfaces.

The second arm of; the bracket extends'upwa'rdly and rearwardly, as shown, at 20 and is at its rear end held-between the outwardlyextending. flanges 21 onv the projection 22 of the, boot 23. A"'suitablebolt 24 serves to 'locklthe two-parts to ether, and a set-screw 25, vextending throng rojecting member 22, serves to adjust the oot 23-relatively to the supporting arm 20.

or lubricant cup 15 is formed in the inner face of the'beari-ng block the upper'part of the At the lower end'of the boot 2.3 is provided I an'inwardly and upwardly extending scraper "26', which 1s of flexible material,

spring steel, and extends inward y a short mg the disks in the heavily thereon as to seriously interfere with provide the flexible scraper as herein shown ing trsnsversely of the arm -35 is provided with an extent of manufacture 'y uneven, with the surfaces are often -eit the result that a rigid sci-s i ll et times be entirel out of enmi ement ell the surface y s c:

of the disknnd at other tunes will beer so its rotation. To overcome this diliiculty I end provide the means described for adjusting the boot which csrries the scropcrto bring the scraper into proper lGlzElJOll with the disk. To clean the remainder of the convex side of the disk. I provide resilient strip or bar 27, which is arched throughout e portion of its length end so mounted that the extreme ends of the bar touch the bracket and the disk respectively when the bar is in its normal position. A. suitable bolt ex l tends through the bar short distance from the upper end thereof 5nd serves to so *urc the some to-the supper A1,. rm 20, and by tightening down this bolt the bar 27 can be straightened to such on extent thut the blade of the some will e gage the surface of the disk from a point 1 cute 0 point beyond that i t re scraper 26. The po tending over that port sl: engaged by the sormer 26 is crubly arched to such n extent that it is held entirely out of contact with the disk.

it is sometimes necer concave side of the disk h n scraper, but conditions sometimes ll-C e to such sin extent While the machine is in hold that these scrapers are unnecessary and it is very desirable to remove the some or to move them out of engegern it with the disks. This I accomplish by providing" a scrsper 29, mounted on a. bar 36, extending equally on both sides thereof, and having one edge slightly curved to conform to the contoinnoi the disk. The end of the l .30 opposite the scraper 29 is bent I in substimtiiilly right angles tot l, as shown :it 31, end the bar is immediately below the bent-over poi" A creel with longitudinal slot ed by a bolt 33, mounted in ii urn). u, su )porting bracket and pr: ided with suitable nut 34. The adjacent face oi the arm 20 is cut away as shown at 235 to permit the bar 30 and its bent-over portion 221 slid 20. The recess no. recess 36, preferlibly curved to conform to the ore of s eirclefend oda )ted to receive the bent-oven. portion 31 of the bar $30 when the "uperis swung about the bolt 33 to move it out oi. its operative position, us shown in dotted lines in Fig. 1' ofqthe drawings.

i lhen the scraper is in use, he bent-over ortion of the bar is pushed u nrnrd so at It lies within the narrow pert oi" the recess 35 to provide the position shown and is retained in this positron by the tension of the spring-bar 30, and

in this position it is entirely out of the way of grass or trash through which the drill may be Passing, and does not gather up such nintcrisl.

'lhusit will be seen that I have provided n'icuns for supporting the disk and the boot from u bracket carried by the drug bar in such a. munncrss to permit of a very (10111- psot zmdnurro arrangement, thus greatly rediuing the obstruction of the 1s between the several disks," and further, that .l hove provided thisklisk with rm improycd cleaning mechanism comprising :1 series ol' edit "tablescrapersinonntcd upon the supporting bracket flDd'iflCll indcpcndmtly inlust-able on the bracket relatively to the disk.

I wish it to be understood that i: do not do sire to limited to the exact details of con-- struction shown and described, l'or olwious modifications will occur to 12, person skilled in the art.
